    Description

      In short: The loggers are altered before the handlers are added to the (root) logger. This leads to propers loggers but without any handler.

      My idea would be to move the propagation to a later point in time. So, I moved it to the method publish(). 

      Here is demo repo to reproduce the issue: https://github.com/mknet/tomcat-webapp-log4j-jul-bridge
